Drosera whittakeri

A rosetted tuberous sundew of South Australia and western Victoria, very common in the Adelaide Hills and Fleurieu Peninsula. It grows as a flat rosette 4–8 cm across through the cool, wet winter and dies back to an underground tuber for the hot, dry summer. It flowers mainly from May to November with up to 20 white flowers.

Lowland to low hills, mostly under about 700 m in the Mount Lofty Ranges. Few records carry an elevation.
